restrictive lung disease Flashcards
what is restrictive lung diseases
lung disease that causes reduced expansion of lunge and/or chest wall
what are some MSK pump disorders
- chest wall (scoliosis, flail chest)
- NM (SCI, GB, MG)
what are some lung disorders
PF
PNA
atelectasis etc
what happens in scoliosis
chest does not inflate or expand, it can retract
-less ventilation due to rib cage not expanding well
what causes chronic interstitial lung disease
known:
- chemo
- toxins
- abnormal immune reactions
- hypersensitivity reactions
- sarcoidosis
unknown:
idiopathic PF
what is the clinical presentation of PFT
- reduction in lung volume and capacity
- elevated RR due to decrease in TV
- airflow maintained but overall volume small
what are common signs of restrictive lung disease
dyspnea
tachypnea
eventual hypoxemia/cyanosis
wheezing/cackles
what happens to lung volumes
- volumes and capacities become smaller
- IRV will be reduced
- cant change depth of breath but can increase rate
what happens to flow rates
-FEV1/FVC ratio may have no change or difference from normal, but volume is lower
what are the two frameworks for long hauler COVID?
- myalgia encephalitis (chronic fatigue syndrome) cog thinking issues
- post acute sequelae (PASC syndrome) brain frog, inability to maintain attention
-palpations, heart problems
treat these people with pulm rehab approach
what is post-exertional malaise
people will feel absolutely wiped for the next day or more following exercise
-for people with this, decrease dosage of whatever they did
low and slow=recommended
what is POTS
postural orthostatic tachycardia syndrome
-lightheaded, palpitations, headaches, nausea/vomit, fatigue
increased risk in those w concussion history and autoimmune disorders
a sustained HR increment > 30 bpm within 10 min of standing
what is the education of POTS
- avoid hot baths/showers, valsava, large meals, dehydrations
- to do: isometrics, crossing and uncrossing
hydration, sodium intake, compression garments, progressive exercise
